Guo Dalu's excitement is indescribable, in any time travel novel, the potato is a big killer that the traverser must introduce, with potatoes, the common people can be saved from hunger, in order to alleviate to a certain extent because of the concentration of land by large landlords and nobles, resulting in the poor have no place to stand, and finally forced to choose a way between starvation and rebellion, which then caused a series of social turmoil.

Only when the common people rely on potatoes to eat their stomachs can they have the energy to engage in other labor and develop all kinds of science and technology, otherwise, the limited labor force will be trapped in the fields and cannot be liberated, and the handicraft industry will not be able to develop.

Guo Dalu actually had a lot of plans in mind, he wanted to dig coal, open mines, smelt steel, improve various tools, make new textile machines, and so on, and all of this required a lot of labor.

However, it was only in Houlong Village that a few small things such as straw paper, snow sugar, and printing were done, which had already made everyone in the village so busy that their feet did not touch the ground, and even girls like the eldest girl and the second girl had to participate in the labor, because even if Guo Dalu's drip irrigation method liberated the villagers from the kudzu grass field, the ration field in Houshan still consumed most of the villagers' energy.

But with potatoes, everything is different!

You know, the potatoes in Guo Dalu's hands, but the varieties that have been improved by the top agricultural technology in the 21st century, are more productive and disease-resistant than potatoes native to the Americas.

One ton, that's 2,000 pounds!

The old farmer in Houlong Village just said that millet is in the best field, carefully fiddling, and the wind and rain are not more than 100 catties.

The yield of potatoes is 20 times that of millet!

How many people can be fed by this!

Guo Dalu immediately decided to plant this potato with his own hands, and fake others, even if he was close to Brother Ruhao, he was not at ease, for fear that they would not realize the importance of this potato and plant it badly.

Planting potatoes is actually very simple, although Guo Dalu is not a farmer's child, but he happened to watch "The Martian", at the moment from the manure field under the mountain behind the village, picked a bucket of manure, evenly spread it in the backyard of his house, and then cut the five potatoes into small pieces, each small piece has one or two buds, and then, the cut side down, the buds face up, buried in the fertilizer, and then spread a layer of broken soil on it, and then poured water.

Five pieces of potatoes, 27 small pieces were cut out, and the rations of the people of the Great Li Dynasty were on these 27 small pieces!

Guo Dalu decided not to do anything recently, and stared at this small piece of land when he saw the sky, so as not to be pecked by insects and birds.

The people take food as the sky, and this potato is the real important weapon of the town!

There must be no mistakes!

Not to mention Guo Dalu's old hen guarding the potato cubes, it is said that the angel of Tianyi Pavilion - Lou Angel, the common name Lou Cen Zhi, is driving the clouds and returning to Tianyi Pavilion in a leisurely manner.

The vial in Lou Cenzhi's sleeve is full of kudzu herbs he collected from all over the world, this year's wind and rain are smooth, and the yield of kudzu is quite gratifying, but the most surprising thing for him is that small Houlong village, Lou Cen thinks that the drip irrigation method will be promoted all over the world, and the herb pills received next year will multiply, and his heart is full of smiles.

Cultivators should be calm and calm, and not be moved by external objects, but this is Kudzu Herb Pill, how many elixirs need Ge Herb Pill to prepare, and it has the title of Ten Thousand Pills, so that the cultivation world knows that the people in the world are dissatisfied, and still forcibly seized the most fertile land in the mortal world to plant Kudzu Grass.

This time, he has made a great contribution, and he may even alarm Fan Puzi, the master of Tianyi Pavilion, if he can be received by the pavilion master and have a glimpse of the books in the Tianzi Library, then he may be able to go further in his cultivation!

Lou Cenzhi's heart became hot, who said that cultivators are beyond everything and are not moved by fame and fortune, it is just that fame and fortune in the mortal world are not in their eyes, just like human beings can't see ants fighting for a little crumb, but if it is related to the great cause of cultivation, which cultivator will not be moved? In the cultivation world, it is not uncommon to kill people and seize treasures!

Now, Lou Cen Zhi is already planning to seize the treasure - of course, he is not going to kill people, the treasure he wants to seize is the drip irrigation method invented by Guo Dalu!

How could a mere mortal in the lower realm invent the drip irrigation method? This drip irrigation method was invented by Lou Cen Zhi! Anyway, he had already used a solid Pei Yuan Dan to thank Guo Dalu, as a mortal with incomplete five elements, he couldn't cultivate immortals at all, so what did he want to do with this merit?

Lou Cenzhi's clouds flew until a mountain in front of a mountain, only stopped, this mountain is verdant, under the mountain is a huge lake, named East Lake, Lou Cen went down the clouds, walked to the lake, his hand on the waist of a bamboo card, the bamboo card suddenly lit up with silver light, the lake like a veil of light mist slowly dispersed, revealing a building complex floating on the East Lake.

Horse-head wall, blue tile house, this typical Jiangnan residential group, is Tianyi Pavilion.

A small courtyard surrounds a large courtyard in the center, which has its own pavilions and pavilions, and there is a seven-story small tower in the center, which is the Tianzi Library Building.

Tianyi Pavilion's founder, Fan Qingzi, who had risen three thousand years ago, was originally just a small official of the previous dynasty, but he loved collecting books all his life, and used all his money to buy books, and loved books like an idiot.

It is precisely because of his lifelong obsession with books that Fan Qingzi suddenly realized the Tao from a book in his later years, thus creating the Tianyi Pavilion this school of practice - Tianyi, Tianyi is also a living water, because the study building is most afraid of fire, so Fan Qingzi built Tianyi Pavilion on this East Lake, taking the meaning of water to extinguish fire.

Over the past three thousand years, Tianyi Pavilion has developed extremely prosperous, the practitioners under the door are all people who love books, originally came to seek advice in the name of Mu Tianyi Pavilion's collection of books, after Fan Qingzi became an immortal, there are many book lovers who worship under his door.

Tianyi Pavilion has a rule, that is, the collection of books is open to everyone, but can only be borrowed and can not be taken away, and the borrower must also give books to Tianyi Pavilion, over time, Tianyi Pavilion collection of books ranks first in the world, and now those who practice under the door of Tianyi Pavilion are all reading books and enlightened.

Lou Cen Zhi walked through the waves, passing through the small courtyard on the periphery of the Tianyi Pavilion - it was the house of the cultivators, and from time to time someone greeted him, but more cultivators buried themselves in the books, or read aloud, or frowned and pondered, hoping to realize the great way from the classics.

Everyone says that cultivating immortals is good, where do you know the difficulties of cultivating immortals, I don't know how many cultivators, after getting a glimpse of the avenue, it is difficult to make an inch of progress for many years, and finally die and the lights go out, but they only live a few years longer than mortals.

His own comprehension is insufficient, so he has to rely on external forces, so in Tianyi Pavilion, in addition to collecting books, another important thing that cultivators value most is the elixir - in fact, not only Tianyi Pavilion, which sect of cultivation is not like this? Classics, elixirs, and magic weapons, all three are indispensable, of course, the demons in the lower realm are different, and they cannibalism can also increase mana.

The cultivators under the Tianyi Pavilion saw Lou Cen Zhi returning with a smile, and knew that the immortal grass harvest in the mortal realm was good this year, and he would soon be able to distribute the medicinal herbs belonging to his name for practicing pills, so many cultivators nodded with a smile on their faces and nodded to Lou Cen Zhi who was passing by in a hurry.

Lou Cen Zhi has been coming to a small island in the middle of the East Lake, this island is more than 100 acres large, the aura on it is very sufficient, it is the place where the spiritual veins of the surrounding Siming Mountains are located, there are many fairy grass and spiritual trees planted on it, the aura that is so thick that it cannot be dispersed, just smelling it, it makes people feel fluttering.

Lou Cen Zhi stopped outside the chaimen outside the island, he knew that although the island seemed to be peaceful, there were countless other forbidden magic arrays, and if he broke indiscriminately, he would definitely be doomed.

He cleared his throat and saluted: "Uncle Yu Qingshi, Lou Cen Zhi, a disciple of the outer gate of Tianyi Pavilion, received Ge Cao Dan from the Nether Realm and returned it, and he came to pay for his life. As he spoke, he took out the vial of Kudzu Dan from his bosom and held it in his hand.

There was a grass hut on the island, and a childish voice came from inside: "Xiaolou, put down the pill bottle and go to yourself, I'm busy dispensing pills here." ”

Lou Cen Zhi knew that every time the herb harvest season was the busiest time for Yu Qingshi, who was in charge of the medicine garden in Tianyi Pavilion, he had to mix dozens of immortal herbs one by one, not only to prepare for his own alchemy, but also to prepare hundreds of immortal medicine formulas for the upper and lower cultivators, and to prepare the immortal grass spirit trees that needed to be planted in the coming year, and he was very busy.

At this time in previous years, Lou Cen Zhi naturally put down the bottle and left, no longer bothering Uncle Yu Qing, but this time he had something important to tell him, and even expected to be able to see the master of the Heavenly Pavilion with this, so he took out the small jade bottle containing Kudzu Dan and said: "Uncle Yu, this year's Kudzu harvest is different from previous years--"

Before his words fell, a small figure sprang out from the straw shed, and shouted in a hurry: "What happened to this year's kudzu harvest? But the harvest is not in arrears? Oops! Oops! Several people in the pavilion are in urgent need of kudzu grass pills this year, if the harvest is in arrears, how can they get it? Do you still want me, an old immortal, to pull down this old face and go to those old thieves in the Qita Temple to ask for it?"

I saw this self-proclaimed old immortal, just a drooping boy, wearing shorts and a gown, with a shepherd flute inserted in his waist, this little boy is the uncle of Tianyi Pavilion Yu Qingshi, don't look at his appearance like a child who has not grown up, in fact, the generation is extremely high, he is the first generation of Tianyi Pavilion Pavilion's shepherd boy, often when herding cattle, secretly run to the library building, listen to the master read books, when the master of the Tao attained, he also had a flash of inspiration, enlightenment.
